Title: Semiconductive sensor amplifying circuit
Inventor: MIZUNO CHIAKI
IPC: G01D3/028
Filed: 1987-04-13
Abstract: PURPOSE:To obtain output reduced in an error, by forming an amplifier into two stages and providing a filter circuit equipped with a condenser between two stages. CONSTITUTION:When acceleration acts on a semiconductive sensor, stress acts on a diaphragm part by the inertia of the free end 12c and wt. 12b of a cantilever 12 to deform said diaphragm part. Each diffusion resistor 12e changes in its resistance value by piezoelectric effect due to the action of said stress. Whereupon, since the resistance value of each arm of a bridge circuit 10 changes, the voltage change proportional to the change in the resistance value is generated at both detection terminals of the circuit 10. This voltage change is operated and amplified by a differential amplifying part 20. The output of the differential amplifying part is applied to a filter part 30 and the DC component of the temp. drift of each diffusion resistor and the offset drift of the amplifying part 20 is removed by a condenser C and a resistor R7 and the electromotive force of a constant voltage source E1 is added as the DC component and further amplified by an amplifying part 40 to be outputted. By this method, output reduced in an error is obtained.

Title: Circulation terminal device
Inventor: TSUSHIMO YOSHIYUKI
IPC: G07F9/00
Filed: 1982-05-28
Abstract: PURPOSE:To realize the miniaturization and a low cost as well as to improve the operability for a circulation terminal device which is used in case the names and prices of goods are varied by the time period, by loading automatically only an information assigned to key group from outside in accordance with an operating time period. CONSTITUTION:A dislay 11, a printer 12 and an external storage device 13 are connected to the main body 14 of a price look-up type cash register. The real time information is set successively to a CPU1 from a real time counting part 5. When this time information varies, it is compared with the switching time which is previously set within an RAM3. When the coincidence is obtained, the CPU1 changes the assignment of a price look-up key 6 on a keyboard 10 and then uses a code corresponding to the switching time point to load the number code and unit price of the article in the corresponding time band to the RAM3 from the device 13. When this loading is over, the contents of loading are displayed at a display 11. Then the loaded assignment information is allotted to the corresponding keys P1-P30 of the key 6. Then the subsequent accounts are processed.

Title: Level detection circuit
Inventor: SUZUKI HIDEYUKI
IPC: H03G3/20
Filed: 1994-04-28
Abstract: PURPOSE:To provide a level detection circuit in which the errors of high-speed signals are small. CONSTITUTION:This circuit is constituted of a diode 2 for adding input signals (a) to one end of parallel circuits 4 and 5, a detection terminal 3 for detecting the potential of a capacitor 4 and a circuit composed of diodes 8 and 9 and a resistor 7 parallelly connected to the parallel circuit and the signals (c) whose phase is opposite to the input signals are added from one end 10 of the diode 9. A current larger than the current allowed to end 10 of the diode 9. A current flow to the resistor 5 is allowed to flow to the resistor 7 at the time of charging and the diodes 8 and 9 and the resistor are practically cut off from the parallel circuits at the time of discharging. In a charging process, by adding the resistor 7 of a resistance value smaller than the resistor 5, the internal resistance of the diode 2 i.s made small. In a discharging process, the diode 8 is cut off from a discharging circuit and the charge of the capacitor 4 is discharged by the resistor 5. Thus, since a charging time constant is made small by the diode 2 whose internal resistance is small in the charging process and the diode 8 is cut off from the discharging circuit in the discharging process, a discharging time constant is adjusted to a desired value independent of the charging time constant.

Title: Method for controlling fine particle flow
Inventor: CHIBA YUJI
IPC: B05C19/00
Filed: 1985-04-30
Abstract: PURPOSE:To transfer fine particles as a uniformly dispersed ejected flow or a supersonic beam by evacuating the downstream side of a contracting and expanding nozzle provided at the flow passage and passing the fine particles through the nozzle. CONSTITUTION:The downstream side of a contracting and expanding nozzle 1 provided at the flow passage is evacuated and fine particles are passed through the nozzle. Consequently, since fine particles can be transferred as a uniformly dispersed ejected flow or a supersonic beam, the fine particles can be independently transferred in the space at high speed. Accordingly, the discharge of fine particles can be easily prevented by the evacuation of the downstream side. Furthermore, active fine particles can be transferred under such conditions to a collecting position and the blowing region can be precisely controlled by controlling the surface to be irradiated with the beam.

Filed: 1994-04-28
Abstract: PURPOSE:To obtain a modified luminous pigment greatly improved in water resistance, emitting light for a long time and harmless to the human body by immersing a luminous pigment comprising a metal oxide doped with a rare earth element in an aqueous acid. CONSTITUTION:A luminous pigment comprising a metal oxide doped with a rare earth element is modified by bringing it into contact with an acid or an acid-generating substance in the presence of water. As the metal oxide, calcium, strontium, barium, aluminum and cerium oxides are suitable, and as the rare earth element, Eu, Tb, Dy, etc., are suitable; however, as the pigment, particularly the one containing strontium oxide, alumina, and 0.5-5wt.%, based on the total weight, Eu and Dy is preferably used. As the acid, those that react with the metal oxides to form water-insoluble products can be used, among which a phosohoric acid compound is preferably used in particular. The luminous pigment is modified by immersing it in a solution of about 0.5-4wt.% acid in about three- to ten-fold by weight of water for treatment at 50 deg.C or above for about 10 to 60min and then drying it.

Abstract: PROBLEM TO BE SOLVED: To prevent erroneous control in a satellite by detecting the existence of the abnormality occurrence by monitoring reference telemetry data being an output signal of a reference telemetry generating circuit, and automatically selecting a normal user interface device when abnormality is caused. SOLUTION: An integrated control device 1 extracts reference telemetry data from received data to judge whether or not a normal value is shown by a reference telemetry judging circuit 21 to perform the same control as a convential device when a judging result is normal. If the reference telemetry data is judged as abnormal, the integrated control device 1 performs control for switching a user interface device 4a to the other interface device 4b being a redundant system, and continues the same control as before abnormality is caused. This constitution can continue control without receiving support from a ground station.

Abstract: PURPOSE:To prevent abnormal stop and fluid compression owing to oil foaming by preventing a fluid from returning from a fluid line to a discharge side of a compressor upon stop of an air conditioner. CONSTITUTION:When a stop instruction is received during operation of an air conditioner, a compressor 1 is made to operate at a low capacity for a predetermined time, and hence a remaining pump-down operation is performed where a motor driven expansion valve 8 or 13 on the side of a condenser is opened while a motor-driven expansion valve 13 or 8 on the side of an evaporator is closed, and thereafter the compressor 1 is stopped. A fluid refrigerant stored in a heat exchanger, etc., before the stop of the compressor 1 is received by a receiver 9 and is prevented from returning to the compressor 1. Particularly, a remaining pump-down operation is performed for a long time under conditions where the compressor 1 is frequency started and stopped, to substantially completely discharge the fluid refrigerant in an accumulator and the compressor 1. However, under conditions where the refrigerant is clearly dried, the compressor 1 is stopped according to a stop instruction without performing the remaining pump-down operation.
